. To all `whom t may concern.:

Be it known that I, EDWARD KENER, J r., a citizen of the United States, residing at Buffalo, inthe county of Erie and State of New York, have invented new and useful Improvements in Combination .Gas and Solid Fuel Ranges, of which the following is a specification.

This invention relates more particularly toa stove or range designed for burning either solid or gaseous fuel according to whichever is more convenient or available.

It isthe object of this inventionto pro- -vide a range of this character which can be produced at comparatively low cost, which has a grate for burninghard fuel and a burnerl for gaseous fuel, which can be readily converted for utilizing one or the other form of these fuels, and which gas burner can be readily and quickly placed 1n .lines in Fig. 1. Figs. 4 and 5 are horizontal sections taken on the correspondingly numbered linesin Figs. 2 and 3. Fig. 6 is a fragmentary vertical longitudinal section of the stove, on an enlarged scale, taken on line 6 6, Fig. 2 and showing the im-V proved adjustable'damper. Fig. 7v is a vertical transverse section on line 7 7, Fig.

G. Fig. 8 is a fragmentary vertical transverse section taken on line 8-8`, Fig. 4 and showing the improved means 'for removablyv and adjustably mounting the gas burner in the range. Figs. 9 and 10 are fragmentary vertical. longitudinal sections taken on the correspondingly numbered lines in Fig. 8

llooking in the direction ofthe arrows associated with these lines. j

Similar characters of reference indicate corresponding parts throughout the several views. Y i

l represents the re box or poty ofthe range or stove, 2 thegrate at the lowerl end of the fire box and 3 the ash pit arranged below the grate all of which parts may be of any suitable'andv well yknown construction..V As shown inthe drawings,the rear .trolled by dampers or slides 9.

transverse wall or side et of the fire box is lined with fire brick and its front transverse side 5 is constructed in the form of a hollow water chamber through which water is circulated and heated by the flre in the pot or box'in a well known manner. In front of thel water chamber is arranged the breast 6 of the stove which is separated from the water chamber by an intervening air chamber or passage 7 and provided with air inlet openings 8 which are adapted to be con- The air entering through these openings passes into the air passage 7 and thence downwardly in the same into the ash pit and thence upwardly past the grate to the solid fuel in the fire box for aiding in the combustion of the solid fuel. By separating the breast of the stove from the lwater box so as .to form an intervening air passage between the same the heat of the fire box is prevented from warping this'part of the stove and the air passing downwardlv between the breast and y thewater chamber is heated preliminary to mixing with the solid fuel, thereby putting the same in the-best condition for promoting-combustion and economizing in the consumption of fuel.

10 indicates the oven which is preferably arranged in the rear part of the stove and above a line extending horizontally over the y top of the tire box.

- l1, 12, 13, 14 indicate the horizontal main flue, the horizontal top flue, andthe front and rear vertical transverse flues, respectively, whereby the heat from 'the fire box or other heating ydevice is conducted around the bottom, top andftransverse front and rear sides ofthe oven. The main flue 11 communicates atits front end with the top of the fire box and extends with its rear part underneath the lower side or bottom of the oven, the upper or top flue 12 extends horizontally over the top of the oven, the front transverse flue 13 is arranged transversely in front of the oven and connects than the rear "part thereof, "this vfront part extending nearly to the lower end oftheV front vertical Hue 13 and some distancebeyond the rear side of the lire box. Y nThe bottoni of the main `Hue is constructed to grad'- ually'risefrom the ire box to the lower end ofthe rear vertical flue, as showiiin Fig. 1;

By this means the heat developed yin thefire bjoX or other heating device is caused to rise gradually vor by successive steps and ,follow its natural tendency to go upward without interference, thereby, promoting 4thegdraft through; the stove and increasing the heating efficiency'of thesame, A

represents. a smoke box-arranged behind the rearvlongitudinal side of the oven and the upper horizontal and front vertical fines.

Theupper part of this smoke box communi- Cates with the central rear part of the top flue 12-. by means of a passageway-wand the rear end ofthe lfront vertical {iue 13 communic'ates with the smoke box by means of apassageway 17.` In its top the smoke borg'is provided with an outlet or damper openingl8'tlie upper end of which is surrounded by a'sinoke pipe collar 19 whichv connects with u the lower end of a Smoke .pipe 20 whereby the 1 products of combustion of the range or stove are carried off to the chimney. l

f At the lower end of the front vertical flue '13 isv arranged a by-pass damper :oi'- valve 21 which is adapted to'open or close the bypass 22 between the' lower end ofthe front flue,v and the central part .of the main flue this damper being preferably pivoted at its front endy adjacent to the front wall of this flue and adapted to be either raised into its inoperative vertical position for opening the passage, as shown by dotted lines in Fig.

1 or turned finto' a horizontal position for closing the passage 22, as indicated byfull lines in this' figure. This valve is shifted -for this purpose by means lof a horizontal transverse rod 23 connected with this damper or'valve and provided at its front end with a handle 2 4 for manipulating the same.

l/Vithin the upper flue 12 is arranged an upper1 baflie 25 'which preferably extends' from the lrear longitudinal` wall of this fiue' adjacent to the rear edge ofathe rearpassage 16 forwardly and inwardlyto a 'point appreXimately in the centerof this flue. Vithin"'the'upper front Aflue 18 is also arranged a'bafle 26 which extendsfrom the rear lonaV direct communication between the fire pot andthe smoke vpipe atl which time the heat` and products of combustion pass from the, top'V of' theffrerbox rearwardly throughl the` high pm @if 'the'mai aus, thence into the adjacent shallow rearpart of this Yflue and thencetlie. bulkof thisheata-nd the prodj uctsof` combustion escape through the lpassageway v22 4into the upright front f1ue13 aiidvpass from thence through thepassageway`17 inthe rear longitudinal wall thereof intov thesmoke boxjand then out through the smoke pipe to the chimney. After the fire has been lstarted andfburns sufficiently bright the vby-pass damper 21 Yis closed. so

that. direct communication between the fire boX and the .smoke pipe is cut' o and thereafter' the heat and-products of. combustion` are' all` compelled to pass rearwardly underneath-'the bottomV of the oven, thence upwardly through the rearrfiue l14 along' the rear-transverse wall of the oven,`thence for- Y wardly through the top flue 12fand over the top of-the oven until. they yreach the een# tral part of this last mentioned ilueat which place the Vupper baffle deflects the heat and gases toward the frontY longitudinal wall ofiifthis :passage and part-of the Vheat and gases'pass-aroundithe'front edge of this loaf-1V i'ieI directly :backward through the passageway 16 into the Ysmoke .boxandout 'through the smoke pipe, while another part` ofthe 1 heat and gases continue their forward'moven ment ini the top flue and'p'asszdownwardly 'inv the front flue 3"and around theflower edge of thefro-nt balilathencelaterally rea-i# i ward*throughV thefpass'agewayl-f? into the smoke box and: out through the smoke pipe.v Y.' i, loo top and bottom and the front and rear trans` 1f It will be lobservedthatlbyfthis means the verse w-lls'of the ovenvare fall subjected to the heating effect of the heat andigasesgen'- p l grated by the fire, thereby heating the inte rior of the oven uniformly in all parts tliere- .p

The ele- Y top28, thereby furnishing a greater heatingv v' area for a given floor space comparedwithy vatedheating surface may be provided withA openings which' are normally closed by lidsff lVh'en it is desired to utilize ga'sorYY similar/Qfuelas the heating.medium in .place ofv coal or similar solid fuel the range or stove is provided with the following means for this purpose: 27, 27 represent two individual front gasv burners which are -arranged respectively in the main flue underneath the front openings in the stove top 28 which are normally closed by the lids 29, and 30 represents an elongated multiple burner which is arranged in the high part of the main flue underneathboth of the rear openings of the stove top which are normally closed by the rear lids 31, 31. Each of these burners is connected with a ybranch gas pipe 32 which extends horizontally through a vertical slot or opening 33 inthe front longitudinal wall 34 of the main flue and is connected externally of the stove with al horizontal longitudinal gas supply pipe 35. The flow of gas from the supply pipe to the branch pipe is controlled by a valve or stop cock 36 and airis mixed with the gas as it enters the branch pipe by means of an air mixer 37 in the usual and well known manner. When natural gas 1 v is employed as the fuel, the burners are arranged a greater distance below the top of the vstove than when burning articial gas in order to 'compensate for the greater pressure at which natural gas is usually supplied and also enable the natural gas to with the greater volume of air and thus produce complete combustion of the gaseous Vfuel as well as avoiding any odors'fof unconsumed gas andv obtain the; greatest adf vantage from the fuel. When burning naturalV gas lthe burners are, lowered and the branch pipesl thereof are moved. into the lower parts of the slots 33 and when burning artificial gas the Vburners are raised and their branch pipesare shifted into the upper Vparts of said slots. Inorder topermit of placing kthe branch pipesinto either ends of theseslots and covering up the unoccupied parts of thel same lso that air is pre! vented from passing through the same intov the main flue, a shutter 38l is provided whichis preferably constructedV in the form of a plate.v The latter is adapted to engage removably with 'a 'seat 39 vwhich is formed on thel frontlongitudinal wall 34 of vthe main flue by means of pairs of upper and lower lugs and provided on one side of a horizon- Y tal longitudinal central line midway between v55.1Wth a plurality 0f AOpenings 40 eachv of V V40 are below the centervof this plateas indicated vby full lines in Figs.l 8 and 9 at' S5the branch pipes' are shifted into the lupper the `upper and lower edges of this plate which is adaptedto receive one of the branch burner pipes. pipes are'in their loweredposition while burning natural gas the shutterplate is engaged with its seat 39'so that'its openings which vtime the upper part of this plate covers theupper ends of the slots 33. When vby the branch pipes.

VWhen the branch parts of the slots 33 for bringing the burners nearer to the top of the stove while burning artificial gas the shutter plate is reversed in its seat on the stove so that its openings 40 are above the center of this plate and in a position to receive the elevatedbranch pipes while the lower part of this plate covers the lower ends of lthe slots which at this time are unoccupied 1n this manner the same plate can be utilized for closing the unoccupied parts of the slots 40 either when the burners are in a position for utilizing natural gas or artiiicialgas.

At the same time that the burners are shifted from the upper to the lower ends of the slot 40 or vice versa the extreme outer ends of these branch pipes are also shifted from the upper to the lower ends of i the slots 41 or vice versa formed in a bracket 442 securedto the adjacent part of the stove top. The upper and lower ends of each of these bracket slots are enlarged to receive a branch pipe and the central part of each of these slots is constricted as shown at 42, so that Vwhen a 'branch pipe is in engagement with the upper end of a bracket sloty it is prevented from moving downwardly tothe lower end of this slot and when the branch pipe is in the lower end of thispslot the same is held against movement into the upper end of'this slot. VItvwill be obvious that by this means the branch pipes must be wholly withdrawn from the shutter plate and the bracket and then reinserted into the same in the changed position. The shutter plate is securedin place against the front Vwall of the main flue by means of screws 43 as'shown in Fig. 9 or otherwise.

When the burners are not in use the same may be readily Vdisconnected from the supply pipe inasmuch as the branch pipes are connected with the air mixers by means of slip joints. In order to render the burners readily accessible when required for use the same are preferably stored in a compartment 44 arranged underneath the rear shallow part of the'main iiue l1 which compartment is provided with an opening which is nor? mally closed by a door 4,5. When the burners and their supply pipes are'thus removed from the main flue and theheat for cooking purposes is produced by means of coal or wood fire the slots 40 are covered by means of a shutter 46 which is preferably pivoted to' the inner sideyof the front wall of the main flue so that they can be swung over these slots and prevent the admission .of air over the bedv of fuel which otherwise would have the effect of cooling the'fire and interfering with its eiiiciency.

When burning gas the course of the heat is along the underside, rear transverse wall, horizontal top, and transverse front wall of the oven in the same manner as when the 55 terior vof the oven communicates with 'the heat is produced by a solid fuel fire. When burning gas, however, some of the heat may be admitted directly into the oven for the purpose of expediting the cookingof the food therein and for this purpose the bottom Vor underside of the oven is provided with an opening or passage 47 which is normally,

closed by a lid 48 when the solid fuel lire is 'used but which is uncovered when a gaseous fuel is employed. In'order to permit kthis'gas heat to operate most effectively on the food to be cooked the vessels containing the food are preferably supported upon an open work shelfor rack 49 whichi's supported within the oven ata distanceabove the bottom thereof and provided with'a plurality of openings or slots through which Y the vheat of the gas may pass upwardly in passage Y47 but terminates at its edges short ofthe vertical walls `of thefoven,sas shown in Figskl and Bythis means the heat' upon passing from the main flue upwardly through the passageintothelower part of Ythe oven is spread'bytheoven plate 47 and 2- then rises on all sides of the cooking vessel and also passes along the undersideof the same as well Vas over the topthereof, thereby lheatingall of its parts 'e' ed by means of a damper, valve .0r gate V52 which'is constructed in the form of a plate sliding horizontally and lengthwise in a way 53 ontheupper side'of the oven top adjacent to the front longitudinal wall,"

At the outer :end of the lighting channel the bottom visprovided with an opening through which this end of the channel projects, the lower part 73 of this opening being made of semitubular or cylindrical form so that when the bottom 62 is in its normal'raised position this semi-tubular part is 'arranged immediately below the outer end of the lighting channel and forms a complete cylindrical or tubular conduit therewith through which the gas issues vfor convenience in lighting thevsame.

Although the escape of the smoke or other products of combustion from the smoke box through the outlet 18 and into the -smoke pipe may be regulated or controlled in any suitable manner it is preferable to employ the means which are shown in the drawings and which are constructed as follows: 74 represents a damper arranged withinv the collar 19 above the outlet opening 18 and mounted so as tor be rotatable about a horizontal axis so that this damper can either be arranged in a horizontal position in which it obstructs the outlet to the maximum extent, as indicated by full lines in Fig. 7, or the damper may be turned from a horizontal position into a more or less vertical position for clearing the outlet and permit the escape of the products of combustion from the smoke box into the smoke pipe.

At one end the damper is provided with a trunnion 7 5 which is journaled in a bearing 76 formed on the stove top at one end of the outlet, and damper opening and at its opposite end the damper is provided with a damper rod'77 arranged inline with its trunnion and extending through a notch or opening 78 in the Vlower edge of the adjacent part of the. stove pipe collar. At its outer end this damper rod is provided with a crank 7 9 whereby the damper may be turned for regulating the area of the outlet through which the products of combustion escape. At its free end this crank is provided with an oset or laterally projecting handle or fingerpiece 80 whereby the crank may be manipulated. Upon turningthe crank until its straight or even Side opposite to its fingerpiece engages with the stove top the damper will be shifted into its horizontal or maximum closed position, as shown in full lines in Figs. 3, 6 and 7, while upon turning they crank inthe opposite direction so that its olf-set rhandle or ingerpiece engages with the top of the stove, as indicated by dotted lines in Fig. 7, the damper will be arrested in a position in which it inclines and the smoke outlet is uncovered accordingly. By thismeans the attendant by simply swinging the'handle or crank of the damper into either one or the other of its extreme positions will know definitely that the damper is either closed to its maximum extent or '1s open partly suitable for producing a proper draft through :the stove or range, thereby avoiding the necessity of Vany calculation for this purpose. If desired, the crank may be turned so that it projects upwardly from the damper rod in which position the damper would stand vertical and provide the maximum openingl in the smokeoutlet.

In order to hold the damper reliably in its adjusted position without involving the use of any intricate and expensive means rfor this purpose, a retaining device is provided which comprises aflocking collar 81 arranged yon the damper rod within the stove pipe collar and provided on its periphery with a plurality of flat facets 82 which are adapted to engage with a socket 83 arranged in the adjacent part of the stove top and having a plurality of angular facets 84 corresponding to those of the locking collar. Although the number of facets on A the locking collar and the locking socket may be varied it is preferable to provide the locking collar with eight of such facets so that the same is of octagonal form and the socket isl provided withk three Vfacets which correspond to those of the locking collar. Upon turning the damperl by means of the damper rod and handle the locking collar by turning in the socket raises the adjacent end of the damper slightly owing to the cam action of the peripheral form of the collar until the facets of the latter again correspond to those of the socket when the respective end of the damper again drops. Owing to this angular formation of the cooperating surfaces of the locking collar and the socket the weight of the damperis utilized to hold the same yieldingly in the varior range can .be very readily converted Jfor f ing. horizontally from Seid heating device Copiesof this patent may be obtainedior Yuse either as a gasy range or as a 'solid fuel range and Works effectively With either of these fuels, thereby rendering the same particularly ruseful in territories Where gaseous fuel is liable to become temporarily eX-V hausted `and .necessitates utilizing coal or Wood as the fuel for a brieftirne.
